The gas permeability tester is mainly used to detect a professional type of gas permeability material, such as gas permeability, referred to as a breathable test. For foam, leather, textile, paper, cardboard, porous ceramics, etc., the gas permeability tester is very suitable. It is important to monitor the penetration performance of these materials, and the gas permeability test of these materials is required in certain areas. For example, whether the gas permeability of the cigarette paper directly affects the appearance of the smoking, volume

The content of the ingredients of smoke and the content of the flue gas ingredient; and the control of the gas permeability of the textile is directly affected the clothing Key factors of comfort.
3WmTextile Testing Instruments, Testing Equipment Manufacturer For a particular gas permeability of a material having a gas barrier performance, it is necessary to complete the test with a gas permeability tester. The gas permeability tester is mainly used to detect a material having a higher barrier performance, and most of the material is a polymer polymer or a multilayer composite made of a high polymer, such as a plastic film, a composite film, a aluminized film. Aluminum-plastic composite film or paper-plastic composite film, etc.
3WmTextile Testing Instruments, Testing Equipment Manufacturer Fabric gas permeability: Determination of the gas permeability of fabric, China mainly according to the standard GB / T 5453 textile fabric gas measurement, this standard is suitable for a variety of textile fabrics, including industrial fabrics, nonwoven Cloth and other breathable textile products. The gas permeability of the fabric, air permeability of the fabric. With the specified test area, pressure drop and time conditions, the air flow is perpendicular to the rate of the sample through the sample. Specific test principles, as described in the standard: under the specified differential pressure conditions, the gas flow rate is calculated perpendicular to the gas flow flow through the sample given by the sample for a certain period of time. The airflow rate can be measured directly, or it can be obtained by measuring the differential difference between the flow pore size.
3WmTextile Testing Instruments, Testing Equipment Manufacturer Paper threading gas: Paper gas permeability can generally be tested with the gas permeability tester of Girle France test principle. The gas permeability refers to the average air flow of the unit area paper and the cardboard under the unit time and unit pressure difference, and the unit area paper and the cardboard are represented by micrometers / (Pasca Second).
